  • Publication number: 20080264996
    Abstract: A nail gun includes an air concentrating chamber and a main air passage, and the trigger valve is disposed between the air concentrating chamber and the main air passage. The trigger valve includes a valve body, a shuttle valve nested in the valve body, a valve base integrated with the valve body, and a valve bar being capable of pressed and released. When the valve bar is pressed to actuate the high pressure air in the air concentrating chamber to drive the shuttle valve to downwardly move, for guiding the high pressure air in the air concentrating chamber into the main air passage to provide necessary energy for hitting nails. When the valve bar is released, the high pressure air in the main air passage are exhausted, so as to actuate the high pressure air in the air concentrating chamber to drive the shuttle valve to upwardly move to reposit.
